chines for Makin Heels. of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of shoe heels and consists in certain improvements in methods and apparatus for effecting economical production of pasted heels, or heels, the lifts of which are connected toeether by adhesives, with or without the aid iif heel building nails. A chief function of substantial the adhesive in pasted heels is to prevent checking or opening up of spaces between the lifts as a result of varying moisture conditions to which the heel is subjected in wear. Adhesives which are economical and otherwise desirable to use are pastes that set or dry relatively slowly, and satisfact ry re sults require that the heel beheld under pressure while the paste is setting, the usual period pressure ranging from onc-half hour to several hours. It will readily be understood that to hold each heel under pressure for such a period adds materially to the cost of heel manufacture, taxing space and requiring press equipment and labor involving expense. It is particularly burdensome properly to press wedge heels, or those which are higher at the back than at the breast (usually made so by the inclusion of one ormore wedge lifts) and which include practically all womens heels.

One important object of this invention is so to improve methodsof making heels as to effect economies by reducing the time required for setting the adhesive, thereby less ening substantially the heel pressing equipment and factory space necessary for the production of heels. This is accomplished by expediting the setting ofv the paste in the freshly built heels. iii'iother important object is to provide amethod of pressing wedge heels by which the same press apparatus can be employed for effecting equally efiicient pressing of heels of any degree of wedge or no wedge at all. This object is attained by a novel method of stacking wedge heels in a press. A third object of this invention is to provide mechanism with the aid of which a high degree of heel making efficiency is obtained in the practice of my iniprorwl methods.

The fastening of pasted, as well as of dry heels, by one or'two headed nails at the time of the heel building operation is generally practised, the nails serving to hold the lifts against slipping one on another while being luuidled and pressed, before being clinched in the heel compressing operation to restrict expansion of the compressed heel.v The first mentioned function. of the nail may, in some cases, be dispensed with when my improved methods above referred to are used, but when the nailing is desired for the binding of the compressed heel it is preferably effected by an improved method which con stitutes a part of this invention, as does also a novel combination of heel pressing and nailing mechanism herein disclosed for fastening the heel lifts together.

The invention in its various aspects will now be more fully described with the aid of the accompanying drawings and will then he pointed out in the claims.

The heel guide in which pasted heels are arranged for pressure and setting in accordance with this invent-ion may be of any suitable construction. The novel guide 1 the construction of which will later be de- .cribed, is well adapted for the purpose.

In beginning to make heels it is well though not essential, to use a dummy which fits the guide snugly and has a too face adapted to give support squarely to th lower end of the first heel. The first \Yu'ilg."

lon

heel may be placed in the position of the heel 15. The second heel 16 of like wedge is then placed thereon base to base and turned 180 relatively to heel 15. The outer or top lift ends of the two heels are then .in parallelism to receive pressure. Advant-ageously the next heel 17 is superimposed top lift end down on heel 16 with its breastface over the breast face of heel 16. The adjacent wall of the guide 10 then holds the breast faces in alinement. A heel 18 will then be placed in the same relation to the heel 17 as the heel 1(5 occupies to the heel 15, that is. base face to'base face and turned 180 relatively so that the slant or inclination of the base face of one wedge heel offsets the reverse inclination of the other and presents the opposite ends in parallelism to receive the pressure. It will be noted that by arranging the heels as described and shown in Fig. 41: pitched wedge heels, or those having inclined rear ends, may be so stacked that the top lift end of one heel is opposed to the adjacent top lift end of the next. and the larger base end of one heel is opposed to, or substantially covered by, the adjacent large base end face of the next heel. Thus. when endwise pressure is applied to the column of heels the pressure is distributed evenly over substantially the entire area of every heel face, and each wedged and pitched heel as evenly pressed as fiat. straight heels are when stacked in column. It has been found in practice that wedge heels so stacked with like tapers opposed to each other can be subjected to pressure with substantially no slipping of their inclined base faces upon one another. Attainment of this result is facilitated by abutting the breast faces of the alternate pairs. as 16. 17 and 18, 19 against a wall of the guide. at least in the upper partof the guide 10. The invention is carried out as a continuous operation in practice by pressing the heels interinittently, as each heel is introduced. into a close titting guide longer than a plurality of heels, the heels being arranged, as they are in troduced. in pairs having like wedge and having like. end faces in contact. base to base contacting heels being turned 180 relativel to each other.

The. setting of pasted heels is expedited accm'ding to this invention by subjecting the heels simultaneously to pressure anda circulation of air in contact with them. In the example shown, the heels are intermittently subjected to repeated pressure impulses while being held under continuous pressure, while being subjected to a current of air directed both longitudinally and transversely of the column of heels. This method effects a rapid drying of the heels withoutthe checking of the edges. which has heretofore accompanied rapid drying. The checking is avoided by this invention.

1 ,es ae ie by reason of the Way in which the application of pressure is co-ordinated with the expedited drying action. The continuing pressure holds the lifts tightly together as the paste is dried and the repeated pressure impulses, which are cumulative in their effect, tend to squeeze out any excess of paste from the freshly pasted heels and take up any shrinkage caused by drying. Advantageously, the freshly pasted heels are sub jected to repeated pressures as they are forced down through the close fitting upper portion of the friction guide 10. Figs. 1 and i as, for example, the portion extending from the entrance through the first floor. By this time, if heels are introduced at the rate at which they can be built, the paste will have developed considerable adhesiveness. The heels are thus subjected for a time, while under continued pressure, to a cross current of air, the velocity and term perature of which may be varied according to the conditions presented, some pastes and some heel stock being advantageously subjected to a more rapid drying than is beneficial to others. This transverse air current rapidly dries off the surface paste and moisture. Then as the partially set heels progress down through the guide they are subjected to a current of air moving longitudinally of the column'for gradually drying them and setting the paste with the accompaniment of pressure and. frequent pressure impulses which take up the shrink age and keep the spaces between the lifts continuously closed. As the heels" approach the lower end of the guide. they are subjected to a cross current of fresh, dry air to remove any remaining excess moisture" and set the paste firmly while theheels are under pressure. By this invention, a superior pasted heel. which will not check, is produced and the setting. of the paste is so expedited that a much shorter friction heel guide it) may be employed than that heretofore used which commonly extends from the top floor to the basement of a factory and is usually not less than thirty or forty feet long.

lVhen nailed heels are built I find it advantageous to press the heel piles successively into the upper end of the guide with sutli'cient pressure to force the entire column of heels down the friction guide: and to drive the heel-building nail into the pile against the resistance offered by the heel column to further movement down the close fitting guide. Advantageously, the nail or nails are inserted after the application of pressure to force the heel pile into the guide and before it has opportunity to react from the pressure. Also, advantageously, the freshly introduced and nailed heel pile is restrained from reacting from the introducing and nailing pressures; Such reaction, after nail ltltl ing has always heretofore been allowed to occur, as I am advised, thereby loosening the lifts, whereas the present method conserves all the compression effected in the nailing, and then accumulates additional pressure as successive heels are superposed in the guide, pressed and nailed.

An apparatus, with the aid of which my improvements in heel making methods may be z-ulvantageously practised, is fully shown in the drawings and embodies many aluable features of novelty.

The heel guide 10 comprises two parallel channel bars, see Figs. and t3. iach presenting two heel engaging faces forming ap proximately a right angle to engage the breast. face and one side edge of a heel. These are advantageously fluted or chair ncled, as at 20, to present vertical lines of contact with the column of contained heels and air circulating passages between the ribs. The bars are also preferably recessed orcut away along the angle, as at to permit the entrance of air to the heels and particularly to provide air communieation with the exposed surfaces of pitched wedge together to constitute a close fitting friction guide for the heels offering such resistance to the introduction of the heel pile. or the passage of the heel column, or both. as to 111- sure a suitable pressing of the heels as they are introduced or are forced through the guide. Preferably, the friction is maintained and. therefore, the pressure upon the heels rendered continuous throughout the colun'm' by a plurality of spring couplings 525. 2b, and ressure impulses are intermittently transmitted to the entire stack of heels as successive heels are forced into the guide.

Relatively weak springs 28 spread the mouth of. the guide 10 when the bolts are loosened and the. mouth is flared by beveling the upper end faces of the c iannel bars to facilitate the introduction of heel piles, as shown at 29. Ratchet teeth 30 are provided which hold a heel pile against the reaction that tends to raise its upper end above the entrance of the guide and loosen the lifts when the introducing and nailing pressures'are withdrawn. The outer channel bar ears are slotted at 27, where the bolts 25 engage them, to allow that bar to be adjusted laterally for adapting the guide to different sizes or shapes of heels. The heel guide 10 is secured by bolts 32. passing through its rear channel bars, to the POSL of the machine and in alinement with the pressing and nailing devices by which heels are successively introduced into the guide, nailed and pressed down through the guide in column formation.

Below the floor the heel guide 10 is enclosed in an air conductor through which a current of dry air is forced from a. suitable blower 36, the air passing, if desired,

over heating means 38 by which its drying capacity may be increased as required to effect the proper drying of pasted heels passing through the guide under varying weather conditions. Heel making has al ways been adversely affected by unfavorable weather conditions, as for example, in dog day weather it has been impossible to keep up the normal productitm. and the formation of mold upon heels has been almost inevitable. 1 consider it very important to provide heel making apparatus with equipment by which adverse atmospheric conditions can be onset and uniform quality and quantity production be maintained at all times. The conductor is contructed and ar ranged to deliver a cross current of air transversely of the column of green heels. It will he noted that the freshly pasted heels at the upper end of the guide are not subjected to the air current but are allowed to progress under continuous pressure and subjected to intermittent pressure impulses by the means later to he described, while the moisture of the paste penetrates the heel stock and until any excess paste has been squeezed out. The cross currents of air are produced by hatilc plates 37 arranged on opposite sides of the conductor 35 and in staggered relation to each other. A lateral out let conductor all is located at or near the head of the air conductor 35 and is u'ovided ith a damper a l to regulate the flow. The effect of the circulation of dry. and preferably warm, air back and forth about the heels is to dry oti' the excess surface paste rapidly. ithin the conductor 3-35 the air currents have access to the heels through the spaces between. the channel bars and the recesses through the bars. in the case of the pitched heels shown in F t. the air circulates freely in the spaces all around the tapering top lift ends of the heels in the heel guide. The channel bars are formed in sections, and at one or more points with in the air conductor. the sections are separated, as at 42, (see Fig. 3) for a distance to allow free access to all parts of the side of the heel normally guided by them. The joints are preferably staggered to atford a guide on one side of the heel column continuously.

The heels or heel piles i'uay be introduced into the heel guide it) by hand, but I prefer to present heel lifts in properlv arranged piles over the mouth of the. guide by automatic lift assembling mechanism of the type shown in co-pending application of Ralph C. Simmons. Serial No. 81,405.

The mechanism for pressing the heel piles, or it may he heels that have been built: in

compressor by a feeding mechanism the type shown in co-pending application of Thomas Lund, Serial No. 258.849. tiled Oct. 19,1918. It will be understood that neither the feeding and compressing mechanism nor the heel pile assembling mechanism are here-- in claimed, per se, but only as elen'ients of the coi'i'ibination of mechanisms. here disclosed for the first time in the art. so far as I am aware, for producing from separate lifts pasted, cured and compressed heels. The feeding mechanism preferably includes a conveyor of the linli belt type. a portion of Which is shown at (30. and each heel pocket in the conveyor has a rear wall or finger 62 arranged to engage the lowermost heel projecting from the guide and co operate with the opposed wall ot the guide in separating that heel from the column it it should have any tendency to adhere to the latter. The heel pressing; plunger 50 and the conveyor are operatial, by connected mechanism in such time relation that. a heel pocket stands under the guide in when the column of heels torced downwardly. and the conveyor then advances to cause the linger ($2 to force the endmcst heel. laterally oil the column while the column is held by the heel guide. The preservation of the proper time relation between the various units of the system oi machines mav conveniently be controlled trom the indicator lover of the compressing machine. which is actuated once for each reci'procation of the cross head. in the arrangement shown in the drawings. the said lever is connected by a rod to a rock shatt ltliwhich. in turn. ope ates a rod 106 connected to trip the onerevolution clutch controlling the actuation of the plunger 50. Another rod 108. also actuated by the rock shaft 104. may bc utilized to control a. heel building; machine tor supplying the heel piles anton'iatically to the entrance end of the guide 10. when tor adv.antageously pressingthem in the heel guide, successive heel piles must be ditterently presented to the heel guide and must be restored to uniform position'a'ttcr delivery from. the guide. For this purpose I pro )ose the introdiu'ztiou into the described combination of heel positioning mechanism embodying the invention disclosed in the copending application of Fred V. Hart. Serial No. 314-4219, filed July 1919; If automatic positioning mechanism for the heels is not provided, the freshly built blanks may be distributed on a support. as indicated at. 100, see Fig. 2. in convenient proximitv to the upper end of the guide and readily accessible to an: operator who may insert the heel into the guide by hand in proper relative arrangement.

The heel pressing plunger has a removable toot piece which has an arcuate sliding connection with the head. ot' the plunger to allow it to adapt itself to pressing wedge heels presenting pressure receiving surfaces at ditlerent angles to the ver tical. The plunger is reciprocatcd. in a vertical guideway in the machine trams by an eccentric on the shaft 55, whichis c0nnected to a cimstautly driven pulley 56 by a one-revolution treadlc-coutrolled clutch and brake which is fully shown and described in my prior Patent No. 1.087.578.
